I've never faced such problem, but just like you said that was your mistake. As I know wallets do not recover the mistake you did, so I guess those money just got lost forever. Anyway write to the wallet support and I hope they will help you somehow.
I have never experienced such a casualty. so I need to make sure first. I still hear this news first. and I am sure that you are required to start doing business again in order not to be too hopeful.
